Create a midsurface by face pairs

1. Before you define the face pairs, use the Object Display command on the Edit menu to set the translucency of the solid body to 70%. This makes it easier for you to see the resulting mid-sheets relative to the solid body.

2. Use the Midsurface by Face Pairs command to define the face pairs and generate the mid-sheets.

3. In the Midsurface by Face Pairs dialog box, use the Strategy option to specify the approach the software uses to create the face pairs. See Understanding face pair creation for more information.

4. Use the Face Pair list in the Midsurface by Face Pairs dialog box to review the pairs and modify any faces that are paired incorrectly. If you are not satisfied with a given pair of faces, you can:Delete the pair and create a new pair.Modify the face pair by adding or removing faces from one of the sides.Reverse the side 1 and side 2 designations.Use the Replacement Mid-Sheet option to use a selected sheet body as the mid-sheet for a given pair.

5. Examine the previewed mid-sheets and use the Advanced options in the Midsurface by Face Pairs dialog box to adjust the trimming and creation methods, if necessary.

6. Click OK in the Midsurface by Face Pairs dialog box to generate the midsurface.

7. Create a 2D mesh on the midsurface. Make sure to click Edit Mesh Associate Data in the 2D Mesh Dialog Box to set the Thickness Source for the mesh to Midsurface. This instructs the software to apply the calculated thickness from the different face pairs to the mesh.

8. Use the Thickness Information command or the Display 2D Element Thickness option in the Mesh Display dialog box to validate the thickness values. See Creating displays to validate element thickness for more information.

9. Apply boundary conditions to the meshed midsurface and solve the model.
